wiper relay repair

OK - its tight but not that bad.
Its looks like corrosion is your problem.
The corrossion is at the terminals on the bottom of the relay socket.
You need to flip the relay socket which is at the bottom of the tub and check the bottom connections.
I bet you will find a couple of the connections disconnected from corrossion (all green) of which you will need to resolder back.
You may need a wiring diagram for this if there is more than one disconnected.
See E38.org.
Take all the compter modules out to get at the wiper relays. Move the other relays out of your way. You need to get at the bottom sockets.
You can pull on the wiring harness to get more slack in order to be able to flip the socket over..
Take your time, be very, very ,very, very patient and you will suceed.
Clean up the bottom of the tub while you are there. Also unplug the drain hole and make sure it works.
It will take you the whole day. Maybe two if you break something.
Put it all back together when your done.
Rember to take pictures with your digital camera during the process so you can refer back to them if you forget what went where.
You can take it to a mechanic but it will cost you a bundle due to the time involved.
Good luck.
